1st Review of rollcall.tcz :
...@Rich ... Tested rollcall , same results as per your recent post.
.. Some observations :
1) There is no need to supply any argument to rollcall if listing of all servises is required, as ALL is default argument, even ARP is listed in o/p.
2) While a user is connected to TCL server thru APPS for dnloading a TCZ , after DNS field even google dot com is displayed along with IP addrs. ...

**Suggestion** :
It will be better if some headers like IP adrs, Mac , Services , Status etc are provided abv the listed o/p ... in /tmp/rollcall.txt file along with a Date and TimeStamp at the start of file... , in case someone want to archieve or send it to Admin etc.

... All-in-all a slick and good app for a quick checkup of a small network.
.. Some improvements will be coming in future , I know ! ... :)

The command line arguments only effect whether the /tmp/rollcall.txt file is created and what is written to it. If xterm is available
it also pops up a new terminal and displays /tmp/rollcall.txt using the less command. The file just provides a little more detail of
the responses. This is a sample of the /tmp/rollcall.txt file:

Unreachable and Refused mean the port was detected but the service was not detected on that machine.. There are no entries for
192.168.1.4 or 192.168.1.5 because they did not respond to any of the inquiries. The TSTAMP lets you check the clock on the
machines that respond.

Currently rollcall.tcz is available in the TC4, TC9, and TC10 x86 repositories.

Rudock1:
Any chance this tool could be compiled for the Core Pure 64 repository?

I have a Dell laptop that plays by its own rules and this looks like it might shed light on some network details

nothing urgent but thanks for your consideration.

thx
Billy

Absolutely. And since I don't own 64 bit hardware, you just volunteered to help. Install the following extensions:
compiletc.tcz sstrip.tcz squashfs-tools.tcz submitqc.tcz
Download the attached file and execute the following commands:

--- Code: ---tar xzvf rollcall-V0.9.tar.gz
cd rollcall-V0.9/
./CompileRollcall
./PackageRollcall
--- End code ---
Verify the program runs like this:

--- Code: ---sudo ./rollcall
--- End code ---
If all went well:
Copy rollcall.tcz and rollcall.tcz.md5.txt to your tce directory. Use the Apps utility to add rollcall.tcz to your onboot.lst file.
Email the rollcall-x86_64.tar.gz.bfe to tcesubmit _at_ gmail _dot_ com.
You can now remove the build directory like this:

--- Code: ---cd ..
sudo rm -rf rollcall-V0.9
--- End code ---
Any problems or questions, post them to this thread.

If anyone wishes to try this for ARM the same instructions apply but the rollcall .tar.gz.bfe file will have armv in its name.

Hi Rich,

I ran your scripts and submitted the rollcall-x86_64.tar.gz.bfe file as you instructed. It runs well on my system and network:

I really appreciate the advice and very clear directions. It was a great learning experience for me.

I have now added "Learn how the submitqc script works." to my personal bucket list. ;)

thx
